The idea that intelligence can be measured by a single number — your IQ — is wrong, according to a recent study led by researchers at the University of Western Ontario.
The study, published in the journal Neuron on Wednesday, involved 100,000 participants around the world taking 12 cognitive tests, with a smaller sample of the group undergoing simultaneous brain-scan testing.
"When we looked at the data, the bottom line is the whole concept of IQ — or of you having a higher IQ than me — is a myth," said Dr. Adrian Owen, the study's senior investigator and the Canada Excellence Research Chair in Cognitive Neuroscience and Imaging at the university's Brain and Mind Institute. "There is no such thing as a single measure of IQ or a measure of general intelligence."
